George Morris "Morris" Haller (1852-1889) was born in Pennsylvania to U.S. Army Colonel Granville Owen Haller (1819-1897), and his wife, Henrietta Maria (Cox) Haller (1824-1910). The family moved frequently around the country during Granville's military service, and upon his retirement in 1882, they moved to Seattle permanently. Morris studied law in Seattle and became a successful attorney and real estate investor. Several landmarks in the Puget Sound region are named for the family; when the current Trinity Parish Church building was built in 1891, Henrietta donated three stained glass windows to honor Morris, his friend Dr. Thomas Taylor Minor (1844-1889), and his brother-in-law Edward Louis "Edward" Cox (1867-1889). All three were drowned during a bird hunting trip to Whidbey Island.

The plat map pictured here describes land owned by Morris Haller and his wife Anne M. (Cox) Haller (later Grun) (b. 1860). It was filed for recording with the King County Auditor shortly before Morris' untimely death. The land is located on the north edge of Lake Union in Seattle's Wallingford neighborhood. The property stretches west from what was then Bismarck Street (now First Avenue NE) to Clough Street (now Fifth Avenue NE), and south from Lincoln Avenue (now NE 42nd Street) to Spokane Avenue (now NE Northlake Way). This map was surveyed and platted by P. D. Hamlin & Engineers.
